With increase in calorific value of fuels, their adiabatic flame temperatures__________________?
Correct answer: D. May increase or decrease; depends on the quantity of products of combustion
- A. Increase
- B. Decrease
- C. Remain unchanged
- D. May increase or decrease; depends on the quantity of products of combustion
Explanation
Adiabatic flame temperature depends not only on fuel calorific value but also on the amount and heat capacity of the combustion products. Therefore, a higher calorific value may increase or decrease the temperature depending on the combustion-product quantity.
